Answer:
x = - 7, x = 1
Step-by-step explanation:
Given
x² + 6x = 7
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(3)x + 9 = 7 + 9
(x + 3)² = 16 ( take the square root of both sides )
x + 3 = ± = ± 4 ( subtract 3 from both sides )
x = - 3 ± 4
x = - 3 - 4 = - 7
x = - 3 + 4 = 1
Solution set = { - 7, 1 }
Answer:
Option C) is correct
That is the result should be in a difference of squares is
Step-by-step explanation:
To find the result in the form of differences in squares
Given that the expression is (-7x+4)(-7x-4)
( by using the identity
)
Here a=-7x and b=4
Therefore which results as a difference of squares.
Therefore Option C) is correct
That is the result should be in a difference of squares is
